A. bracket 29 is mounted upon tho mm 14 and has a cam lever '30 pivot-eCi lhcroto while connections 31 are M'- rsngoci between the id lever and the bolts in such msnncr that a movement of the rec em. 32 of the lever 30 away from the (-arrying arm 1% rctr cts both of the bolts 22; thus sihm'ing ,ths arm 1-1 and rod 17 to move to choir substantially vertical inoper indicating means positioned either forwardly or at the side of the boat is pro vided with a similar cord 33, itwill be seen that when the pilot desires to elevate any one of the three shoal finders to its inoperative position, it is only necessary to pull upon the cord end 34; forthe desired finder, when the lever will release the bolts 27 add a further pull upon. the cord will ele vate the arm 1%. 1119011 its hinge l5 substantially vertically, While the weight of the blade '20 will allow the rod 17 to move to a vertical position upon its hinge- 18 and lie along side of its carrying arm 14, the entire device being then positioned at the guriwale of the boat.

The usual manner of operating the entire invention is for the boat to proceed ahead at full speed with the forward finder 0peratively positioned in the water, but with the two side finders in their folded inoperative positions. When a. shoal is encountered by the blade 20 of the forward finder, the blade is moved upon its hinge 21 which lowers the wire 23 and bar 19 so that the lug 35 provided upon the bar of the forward finder will engage a pivoted lever 36 m0unt-,

ed upon. the rod 17 of the forward. finder, thus shifting the lever and exerting a pull upon a cord 37 connected to the free end'of the lever and passing across the deck into the pilot house 13 and having its inner end operatively attached to an alarm bell 38 within the pilot house. The bell 38 being rung in this manner whenever the blade 20 of the forward finder strikes a shoal, the speed of the boat will then be reduced as may be desirable and the cord ends 34 will be operated for allowing the side finders'to drop of their own weight to their operative positions in the water. The side finders constituting feelers will then be employed for detcrminingthe position of the shoal and the depth of water covering the same, it being noted that the side finders are laterally shiftahle by the means hereinafter described, the said side finders acting as feelers and the forward finder acting also to give a warning alarm. It will alsoebe noted that the hinge connection 18 of the arm 14 of the forward or how finder is with the rod 17 rather than with the sleeve 26, as is the case in connection with the side finders or feelers which are self feathered.

The disk base 16 of each of the side finders or feelers is swiveliy mounted on the deck by means of centrally arranged pivot bolt 39, while an intervening stationary disk 40 is arranged between the base disk and the clock. This disk 4:0 is provided with a vertical socket 4i and the base disk 16 carries a shiftable pin 42 extending there through, the said pin being adapted for St ing' within the socket 4E1 when the side fin is shifted laterally adjacent the gllnWaic of the boat as shownin dotted lines in Fig. 1, it being understoodthat the pin 42 is normally, positioned within the socket 43 of the stationary disk 40 when the side find ers are laterally arranged, while either of the sockets 41 or 43 may be employed when the side "finders are in'their elevated folded positions; The rods 17 of the side finders being swiveled within the sleeves 26, the said rods are each provided with a cross ipiece 14 having its opposite ends connected by cords 45 with uprightposts 46 mountedless'resistance during the travel of the boat.

As before'stated, when an alarm is given by the forward finder, side feelers may be lowered into the water and will engage the adjacent shoal or sand-bar and by the position of the frames constituting the side feelers, the lateral position of the shoal may be easily determined. During such lowering; movement, the blades 20 will engage the adjacent side shoal andthe lowering movement of the franie will be stopped, which will indicate the side position of the shoal and by the hinged connection of the blade to the rod 17 injury to the side frames will be prevented as the forward movement of the boat will cause the blades to move on their hinged connection with the said rod.

It will thus be seen that a serviceable and eflicient shoal indicating alarm and detector 7 1.
